Hiya,
I found this code snippet(reference http://www.goldb.org) and wish to do more
with it than just send out a Http Get request.I would like to introduce more
traffic -say by downloading files,crawling through all the links,logging in etc
etc,and wish to see how the web server reacts.I'm trying to stress the server
to its limits....appreciate if anyone could provide me code/ideas to inject
into this.
the website -http://ftp.ruby-lang.org/pub/ruby/binaries/mswin32/ selected as
example has many downloads.i tried from urllib import urlretrieve
urlretrieve('http://ftp.ruby-lang.org/pub/ruby/binaries/mswin32/ruby-1.6.4-i586-mswin32.zip','ruby-1.6.4-i586-mswin32.zip'),but
didnt work.....
